I have an mk3 supra i was driving the other day and noticed that my idle was at 1200rpm and my car was already warm so i drove to the next light and same thing so i reved my car up to about 5000rpm and the idle went back down to 500-600rpm does anyone beside me think that this is an early sign of a head gasket problem ?????????????

maybe its a sticky throttle body? or a sensor of some kind

Sounds more like your Idle Speed Control valve needs cleaning.

actaully the other day that happened to me too, it idled at like 1200 rpm and the engine was warm, i reved it for a second and drove it like 100 feet and it went down. I dont know what it was but now it sounds like i need to check those things, Thanks
